Technical Briefing - Deh Cho Bridge Project July 28_ 2009 by dfsdf224s


									Deh Cho Bridge Project
        July 28, 2009
A contract dispute had the potential to disrupt the 2009
construction season. DCBC acted under the contract, with
GNWT support, to direct Ruskin Construction to beging
construction of the work bridge and to begin pier construction.
That work is now underway and a contract has been signed.

Atcon Construction continues its fabrication of steel piers, for
delivery in 2009. It also continues to provide the construction
Dispute resolution mechanisms are built into DCB contracts to
ensure an orderly means of resolving
all disputes, and they are being

GNWT will not comment on contract
disputes between two third parties.
The GNWT entered into a Concession
Agreement with DCBC to construct a $170
million bridge
If at any point DCBC were unable to meet its
     g                              g
obligations under the Concession Agreement,  ,
GNWT would assume responsibility for the
project. That is not an expected outcome.
The GNWT remains informed about the project
through a Department of Transportation team
committed to ensuring high
quality, good value, and a
long service life for the
Deh Cho Bridge
Processes established under the Concession
Agreement ensure the interests of NWT

GNWT worked with DCBC to
provide for independent

reviews of the bridge design
The Deh Cho Bridge is a cable-stayed bridge
design, suitable for spanning a wide river
GNWT undertook a detailed independent review
of the design, and opportunities for improving
the bridge design have been identified.
A final design for the superstructure and deck
is expected by late fall 2009
Any design changes that may be adopted are
not expected to significantly
impact the cost of the bridge.

          delays in steell
fabrication may affect the
overall budget
The project continues to be managed within the

Delays and design changes may have an effect on
the overall budget
◦ Still too early to assess
◦ It is still expected the project will be on budget at
All parties are working
hard to address problems
and have a successful
completion of the project
